Chapter 18, Problem 45E

Interpretation Introduction

Interpretation:

The equilibrium constant expression for the equilibrium equation, ${\text{Zn}}_3{\left({\text{PO}}_4\right)}_2\left(\text{s}\right)\rightleftharpoons 3{\text{Zn}}^{2+}\left(\text{aq}\right)+2{\text{PO}}_4{}^{3-}\left(\text{aq}\right)$ has to be stated.

Concept introduction:

Equilibrium constant is a constant at any point of equilibrium; where, the ratio of the concentration of the products, each raised to power of their respective coefficient, to the concentration of the reactants, each raised to a power of their respective coefficient. Equilibrium constant depends only on temperature.
